Title: Electrical resistor and conducting film
IPC: C03C17/34
Filed: 1964-04-01
Abstract: An electrical resistor comprises a glass or ceramic substrate, preferably an aluminosilicate type glass free from alkali metal ions, over which is applied a primary conducting element consisting of a metal oxide film composed of 100-37% by weight of In2O3 and O-63% by weight of either SnO2 or a combination of SnO2 and Sb2O3 in which the ratio by weight of SnO2 to Sb2O3 is at least 3:2, and an outer modifying and protective metal oxide film composed of 100-50% by weight of Sb2O3 and 0-50% by weight of SnO2, spaced electrical terminals being in electrical contact with both metal oxide films. The metal oxide films may be produced by conventional iridizing techniques and it is convenient to use an aqueous solution in which chlorides of the relevant metals are dissolved in hydrochloric acid, the aqueous solution being atomized with suitable spray equipment and directed on to the heated substrate surface.  A suitable solution for producing the primary conducting element by the atomization method is prepared by mixing 50 ml. of diluted aqueous HCl (1 part conc. HCl to 5 parts H2O) containing 50 gm. InCl3 with 50 ml. of the same diluted aqueous HCl containing 49,5 gm. SnCl4.5H2O and 0,5 gm. SbCl3.  As calculated on the basis of molecular weight conversion factors, the conducting oxide film produced from this solution will contain approximately 60% by weight of In2O3, 39,4% by weight of SnO2 and 0,6% by weight of Sb2O3.  A film forming solution for the outer modifying and protective film may contain 60 parts by weight of SbCl3 to 40 parts by weight of SnCl4.5H2O, the calculated oxide equivalents being 69% by weight of Sb2O3 and 31% by weight of SnO2.  Graphs are given showing the relationship between surface resistivity and temperature coefficient of resistivity for resistors with oxide films of different compositions and thicknesses.  Resistors according to this invention have been produced which have substantially zero temperature coefficients, stable resistance characteristics and resistivity values up to about 6000 ohms/square.

Title: Improvements in heat-treating apparatus
IPC: H05B3/00
Filed: 1920-05-17
Abstract: 143,511. Macdonald, A. S., and Huggins, E. M. May 10, 1919, [Convention date]. Thermometers and pyrometers.-In apparatus for indicating the temperature of metal articles undergoing heat treatment, the articles are supported between clamps 12, 13 slidably mounted on the framework 7 which serve as terminals for the supply of electric current for heating. The lower clamp 13 is brought into position by the treadle mechanism E; the upper clamp 12 which is suspended from a rope 16 passing over a pulley 17 and a drum 18 is brought into a position to accommodate the length of the strip 11 by turning the hand-wheel 19 which rotates the drum 18 through the worm and wheel 20. As the shaft 18<1> upon which the drum 18 is mounted revolves, it turns, by means of the gearing 25, a dial F which has a linear scale G on its periphery and radial lines H corresponding to the length of the article under treatment, and also a temperature scale I. Thus a suitable temperature scale to correspond with the length of the article is brought into posifion each time. The current is then switched on and as the strip 11 expands on increase in temperature the lower contact 13 moves downwards and operates a pointer 26 through the rack 27 and segment 28 which indicates the changing temperature. When the desired temperature is obtained, the strip may be lowered into the oil tank 10. In a modification, shown in Fig. 7, the pointer 26 is pivoted at 48 on a fixed bracket 47 and is adapted to move over a dial F. When the drum 18 is revolved to suit the length of the strip 11, a block 50 is caused to move relatively to the pivot 48 along the slot 49 in the pointer by means of the screwed shaft 45 and the two pairs of gears 43, 44, and 41, 42. The bracket 46 is free to move up or down on the framework 7 with the lower clamp 13 thus causing the pointer to move over the scale F with variations in the temperature of the article or strip 11. The temperature is correct for any length of strip as the distance from 50<1> to pivot 48 is always proportional to the length of the strip 11. The mechanism may be made self-recording by providing a pencil 56 on the pointer.

Abstract: 167,323. Salmon, H. J. May 17, 1920. Rotary machines. - A rotary machine of the kind having an impression cylinder, divided into a number of sectors corresponding to the number of times each sheet is to be printed on, and a transfer drum or drums for transferring the sheet after it is printed on from one sector to the next in rear is provided with a second impression cylinder for perfecting the sheets in one or more colours and with a transfer drum for transferring the sheet to the second impression cylinder from a transfer drum of the first impression cylinder. As shown in Fig. 2, an impression cylinder a is formed with two sectors provided with grippers n, o, and cooperating respectively with printing-cylinders c, d. A sheet fed to the grippers n and printed by the cylinder c may be delivered by a chain i printed on one side only, or may be taken by a transfer drum f and transferred to the grippers o and printed twice on the same side and delivered by the chain i. The sheet may pass from the drum f to a second transfer cylinder g, and thence to a second impression cylinder b coacting with a printing-cylinder e. The cylinder a may be formed with more than two sectors and be used to print severel colours one one side of a sheet. In a modification, the machine is arranged to print more than one impression on one side of a sheet, which is then transferred to a second impression cylinder and has one or more impressions printed on the opposite side. This modification differs from the first in that one more transfer drum is arranged in conjunction with the cylinder a. The printing-surfaces may be of any kind, e.g. lithographic, or offset. Retaining-rolls f coact with the cylinder a to keep the sheet upon it.

Title: Internal combustion engine exhaust gas recirculation control valve  assemblies
IPC: F02M25/07
Filed: 1973-03-22
Abstract: 1383140 Treating charge GENERAL MOTORS CORP 22 March 1973 [17 April 1972] 13731/73 Heading F1B [Also in Division G3] An exhaust gas recirculation control valve assembly uses I.C. engine exhaust back pressure to recirculate exhaust gas at a rate proportional to air-flow to a point downstream of an engine throttle. The valve assembly is used with an inlet and exhaust manifold 10, Fig.1, including an insert 42 in which a recirculation passage has first and second parts 60, 64 connectable with the valve assembly 62. The latter comprises a valve seat 78, Fig.3, between an inlet 72 and an outlet 74, a control mechanism maintaining a constant pressure in zone 92, a spring-closed valve member 80, a chamber 106 communicating through first and second openings with induction vacuum and atmosphere to apply a control pressure to a pressure-responsive member 84 connected to the valve member, the control pressure being regulated by a bleed valve 98. A pressureresponsive device 94 displaces the bleed valve 98 in response to increased pressure in zone 92, to decrease the control pressure resulting in unseating of valve 80 to increase exhaust gas recirculation, the bleed valve being biased to increase the control pressure in response to a decrease in the pressure in the zone thereby decreasing the exhaust gas recirculation. Diaphragms 94 and 84 tend to move in unison to maintain a constant pressure in zone 90 to maintain exhaust gas recirculation at a rate proportional to the rate that combustion air flows into the engine. In a modification a pressure drop in zone 130, Fig.4, causes a spring-loaded central diaphragm portion 138 to unseat a valve 154 to admit air from chamber 142 and openings 146 into chamber 148 causing spring displacement of diaphragm 126 and valve 122 downwardly to reduce exhaust gas recirculation. Chamber 148 may be connected to a carburetter, the manifold 10 or passage 64. In a further modification pressure in zone 174, Fig.5, raises diaphragm 180 and valve member 184 to reduce air-flow through orifice 188 into chamber 190 thereby causing a spring-loaded diaphragm 172 to unseat a valve 168 to increase exhaust gas recirculation. Valve 184 also may control the application of inlet vacuum to chamber 190 by shaping surface 208. Alternatively the connections of pipes 200 and 194 to fittings 194, 198 may be reversed so that valve surface 208 can control the application of vacuum to chamber 202. A valve 206 controlled by temperature may be connected in pipes 194, 196.

Abstract: 1342795 Textile treatment apparatus STX 7 May 1971 [15 May 1970] 13803/71 Headings D1B and D1L A textile treatment apparatus, particularly for dyeing, comprises an optionally pressurized vat 1 which contains the textile material and a bath consisting of a solvent mixture and a treating agent, and from which a portion of the bath is withdrawn via a diaphragm 5, a gate valve 6, a control 7 of the rate of withdrawal of the bath portion, a heat exchanger 8 and a valve 9. The components 5, 6, 7 and 9 may be replaced by a suction pump. The withdrawn portion is fed to a separation column 10 having a rectification section 11 and an exhaustion section 12, one fraction being received in a tank 13 at the foot of the column, which tank may have a heater 15. The contents of tank 13 may be returned to the vat via a pump 17 and an heat exchanger 18 at a rate controlled by the liquid level in the tank through regulator 21. A condenser 25 at the top of the column recovers the other fraction of the withdrawn portion of the bath and delivers it to a vessel 26, a line 27 optionally delivering reflux to the column 12. The fraction of the bath withdrawn may be in the vapour phase, not liquid as in the embodiment shown. In the described embodiments the bath contains a dye which is soluble only in part of the solvent mixture, the rest of the mixture acting as a diluent, which diluent is recycled to the bath so that only the diluent remains at the end of the.dyeing cycle. Examples are given of the dyeing of a polyamide carpet on a jute backing in a bath of methanol and perchloroethylene and a dye soluble in methanol (but not perchloroethylene) in a horizontal autoclave with a flash can as the separation column; the dyeing of polyamide jersey panels in a horizontal drum machine using a mixture of isopropanol and methanol as the dye solvent and monochlorobenzine as the diluent; the dyeing of wool on bobbins in a mixture of isopropanol and methanol as the solvent for the dye and perchloroethylene as diluent, and a final example is given of the dyeing of wool in the form of panels in a paddle machine in the same mixture as for the wool on bobbins. Each bath also contains a small fraction of glacial acetic acid.

Abstract: 1298143 Attaching filter plugs to cigarettes AMF Inc 25 March 1970 [29 April 1969] 14382/70 Heading A2C  Pairs of axially aligned cigarette lengths S1 S2 with an interposed double-length filter F are transferred at a point T from a rotary drum 10 to a rotary drum 1 on which they are united by connector sheets 9 cut by a wheel 8 from a paper strip 7, the sheets being gummed before reaching the transfer point T and being held on a central part of the drum, between aligned pairs of projections 5, by suction applied through holes 106 in the drum and passages 302, 3 in a fixed cylindrical body 2 on which the drum is rotatable. The cigarette pairs and filters are deposited on the drum at the trailing sides of the projections 5 and held by suction applied through holes 205 in the drum and passages 102, 202, 3 in the body 2. The passages 102, 202, 302, which are in the form of arcuate recesses on the surface of the body 2, terminate at a point where a cigarette pair comes into contact with a surface 111 so that the suction holding that pair is interrupted while the pair is rolled for the uniting operation. The surface 111, which may be heated, is formed on a member 11 which is pivotally mounted to facilitate cleaning &c. Suction is also interrupted whilst the filter portion of a cigarette pair is engaged by a spring-pressed lever 14 so that in the event of the absence of a connector sheet 9 the two cigarette lengths will fall away. Also, should a connector sheet be present but the filter missing, the lever 14 will so deform the assembly that the cigarette lengths will not be in contact with the drum at the point at which suction is resumed through the passages 105, 502 and the assembly will fall away. The lever 14 may be withdrawn from the drum to allow cigarette assemblies to fall for sampling. Properly united assemblies are carried to a transfer point R at which they are removed by a drum 13. In a modification, the fixed body 2 controlling suction by valving action with the rotary drum 1 is replaced by a fixed member with a planar surface having ports coacting with a ported surface on one side of the rotary drum 1. Ports are also provided for blowing to clean the passages 105, 106 after the cigarette assemblies have been removed by the drum 13.
